CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 474,261, dated May 3,1892.

Application filed September 2l, 1891. Serial No. 406,417. (No model.)

To all whom zit may concern:

Be it known lthat we, JOHN W. 4NEUMANN and JOHN R. PELANZ, ofLouisville, in the county of Jefferson and State of Kentucky, haveinvented a new and useful Improvement in Oar-Brakes, of which thefollowing is a specification.

This invention relates to an improved brake for street-cars and thelike, the object of the invention being to provide a novel form of brakefor the motor-car which can be quickly and easily applied by theoperator, and a further object of our invention is to providev a novelform of mechanism for the trail car or cars, whereby as the motor-car isstopped the coupling devices will operate to apply the brakes to thetrail-cars.

With these various objects in view our invention consists in thepeculiar construction of the various parts and the novel combination orarrangement of the same, all of which will be fully describedhereinafter, and pointed out in the claims.

In the drawings forming a part of this speciiication, Figure l is abottom plan view of the motor-car and a portion of the trail-car, saidcars being coupled. Fig. 2 is a vertical longitudinal section of saidcars in a coupled condition. Fig. 3 is a detail view of the couplingdevice and Fig. 4 is a top plan view of the foot-lever.

Referring to the drawings, A indicates the motor-car, provided with theusual dash a. Upon the under side of the car are arranged the paralleloperating-rods B B, said rods being pivoted to the said bottom near therear end of the same, and these bars are connected and braced by meansof the cross-pieces b ZJ. A transverse shaft C is attached to theoperating-rods about midway between the wheeltrucks, and to said shaftare pivoted the pitrnan-rods D D, the opposite ends of said rods beingconnected with brake-beams E E, which are hung from the bottom of thecar, and carrying shoes e e, which bear upon the wheels, as usual.

A spring F is attached to the bottom of car and bears upon the inner orrear crosspiece b to hold the operating-bars normally in an elevatedposition, and while the bars are so held the shoes are held out ofcontact with the wheels.

In order to apply the'brakes, it is only neces- -sary to depress thefree or distal end of the operatin g-bars, which projectforward beneaththe dash-platform, and in order to so operate them We provide theangular-shaped leverrods G G, which are pivoted at their upper ends tothe dasl1-boaid,and are pivotally-connected at their lower ends to theouter or forward cross-piece b, the platform being slottedlongitudinally to permit the passage of said lever-rods. A transversebar G connects the lever-rods G G at the bends of the same, and saidrods are also coiled at that point to provide a passage for the saidbar. The foot is placed upon this transverse bar when the brakes areapplied, said bar insuring a uniform action of the lever-rods G G.

From the above description it will be understood that the shoes arenormally held away from the wheels by means of the spring F, and alsothat the brakes are applied by pressing down upon the bar G with thefoot, thereby depressing the operating-rods, lowering the common pivotalpoint of the pitmen, spreading the beams, and applying the shoes to thewheels.

The trail-car A is provided with operatingrods, pitmen, springs, dac.,the same as the motor-car.

A'wedgeshaped draw-head Il is pivotally attached to the rear end of themotor-car, said draw-head being capable of moving vertically andhorizontally, as desired. This draw-head is arranged with its broaderend foremost, .and at its narrow end is provided with avertically-movable coupling-pin H', which is provided with a T-shapedhead and a circular base, as clearly shown. The trail-car A is providedwith a draw-head H2, which is slotted longitudinally, as at h, toreceive the coupling-pin, and said head is also formed with dependingsides 71,', which act as guides for the draw-head I-I as it slides uponthe drawhead H2. A friction-roller K is arranged between the free endsof the operating-rods of the trail-car and beneath the draw-head of saidcar.

In coupling the cars the head of the coupling-pin is inserted in theslot of draw-head and then locked therein, as shown, the wedgelshapeddraw-head resting beneath the slotted draw-head. A spring L bears uponthe slotted IOO ` draw-head, thereby holding the Wedge-shaped draw-headdown upon the friction-roller, and as the motor-car is braked thetrail-car moving forward will cause the Wedge-shaped drawhead to rideupon the friction-roller, thereby depressing the forward ends of theoperatingrods and applying the brakes of the trail-car a very short timeafter the brakes have been applied to the motor-car. A locking-catch Mis pivoted to the frame of the trail-car just above its draw-head, saidcatch being adapted to be swung outward and engage the head of thecoupling-pin when it is desired to back the train, the catch serving tokeep the wedgeshaped draw-head from riding upon the friction-roller andapplying the brakes.

Having thus described our invention, what l. The combination, with thebrake-beams carrying shoes, of the pitman-rods connected therewith andthe operating-rods connected with the pitmanrods, said operating-rodsbeing pivoted at the rear ends and free to be depressed at their forwardends, substantially as shown and described.

2. The combination, with the brake-beams, of the pitman-rods attach'edthereto, the pivoted operating-rods connected with the pitman-rods, aspring adapted to maintain said rods normally in a raised position, anda depressor adapted to bear upon the forward ends of the operating-rodsto apply the brakes, substantially as shown and described.

3. The combination, with a draw-head having an inclined lower face, of acoupling-pin connected with the free end thereof, a longi`tudinally-slotted draw-head, the pivoted operating-rods, thefriction-roller, pitman-rods, and brake-beams, all arrangedsubstantially as shown and described.

4. The combination, with the brake-beams, pitman-rods, operating-rods,and frictionroller, of the longitudinally-slotted draw-head havingdepending sides, the Wedge-shaped draw-head, and the vertically-movablecoupling-pin having a T-shaped head, all arranged substantially as shownand described.

5. The combination, With the brake-beams and pitman-rods, of the pivotedoperatingrods and the lever-rods adapted tol depress the free ends ofsaid rods, substantially as shown and described.

6. The combinatiomwith the operating-rods and attached parts of thelever-rods, of the dashboard, the slotted platform, and transverse bar,all arranged substantially as shown and described.
